The 'spontaneous' development of pituitary tumours has been studied in the Wistar–Furth strain of rat. In females aged 64–135 weeks the incidence was as high as 69% whereas in males aged 72–116 weeks only 6% developed tumours. Hyperprolactinaemia was invariably associated with these spontaneous pituitary tumours but excessive secretion of growth hormone (GH) was found in one animal only. Bromocriptine inhibited secretion of prolactin and DNA synthesis of the tumours. In a mixed GH- and prolactin-secreting tumour transplanted to a peripheral site, bromocriptine reduced the size of the tumour as well as the secretion of both hormones. Oestradiol reversed the inhibitory action of bromocriptine on prolactin secretion and tumour growth but failed to influence the reduction in GH secretion caused by the drug.
Journal of Endocrinology is committed to supporting researchers in demonstrating the impact of their articles published in the journal.
The two types of article metrics we measure are (i) more traditional full-text views and pdf downloads, and (ii) Altmetric data, which shows the wider impact of articles in a range of non-traditional sources, such as social media.
